60  *
61  * Slot 1 store with slot 0 load
62  * A slot 1 store operation with a slot 0 load operation can appear in a packet.
63  * The packet attribute :mem_noshuf inhibits the instruction reordering that
64  * would otherwise be done by the assembler. For example:
65  *     {
66  *         memw(R5) = R2 // slot 1 store
67  *         R3 = memh(R6) // slot 0 load
68  *     }:mem_noshuf
69  * Unlike most packetized operations, these memory operations are not executed
70  * in parallel (Section 3.3.1). Instead, the store instruction in Slot 1
71  * effectively executes first, followed by the load instruction in Slot 0. If
72  * the addresses of the two operations are overlapping, the load will receive
73  * the newly stored data. This feature is supported in processor versions
74  * V65 or greater.
75  *
76  *
77  * For qemu, we look for a load in slot 0 when there is  a store in slot 1
78  * in the same packet.  When we see this, we call a helper that probes the
79  * load to make sure it doesn't fault.  Then, we process the store ahead of
80  * the actual load.
